In general, the sealing ring of alkaline battery be there are the plastics with certain resilience to be made, such as PP and nylon, Ke Yishi
Nylon66 fiber, nylon 610, nylon 612, nylon 1010.
Battery is during long term storage and use, because the reasons such as the self discharge of battery cathode, impurity liberation of hydrogen make in battery
Air pressure increase.In order to make cell safety use, the sealing ring of present alkaline battery be designed with substantially thickness about 0.1~
The weak floor of 0.3mm.Weak floor and sealing ring single injection-molded.
PP or nylon material are easy aging in lye, and the aging phenomenon of weak layer surface can show even more serious, and
And since inside battery air pressure makes the sealing ring moment of battery bear an outside stress, this can lead to the weak floor of sealing ring
Accelerated ageing.If meeting severe external environment, such as high temperature, high humidity, the aging of sealing ring weak floor is with regard to even more serious.
After sealing ring weak floor cannot bear cell internal pressure, weak floor will be broken, inside battery gas and electricity
The electrolyte in pond will be released out of battery, and such alkaline battery occurs as soon as leakage.
In the past, we were generally by reduction gas generated (adjustment house formulations, reduction impurity introducing etc.), sealing ring
Protective rubber is applied at weak floor, changes the schemes such as sealing ring material to realize the promotion of leak resistance after its storage.
Invention content
Technical problem to be solved by the invention is to provide a kind of electricity that can be constantly discharged to inside battery gas
Pond collector avoids the increase of inside battery air pressure, while can prevent the solution leakage of inside battery again.The present invention is further

The further preferred embodiment of the present invention is:Alkaline battery, it is characterised in that any described including claim 1-7
Battery current collector
Compared with prior art, it is an advantage of the invention that using breathable lamina made of polytetrafluoroethylene (PTFE) or breathable films knot
The air hole in sealing ring is closed to substitute the weak floor in conventional seals circle, using in polytetrafluoroethylene (PTFE) alkali resistant, high temperature resistant, plastics
Advantage least easy to aging makes the service life of collector greatly increase.In traditional handicraft, released because inside battery gas is unable to get
It puts, control interior gas amount becomes the bottleneck of alkaline battery development.One comes the degree of purity to raw material, box hat and conductive nail coating
Consistency, production process cleannes, production equipment material and wearability require it is all very high, this just considerably increase raw material at
This and production management cost, product quality are influenced very big by human factor.Two come in order to keep internal gas yield small, it is ensured that electricity
The safety in pond, the resistance to leakage of the resistance to ag(e)ing of sealing element, battery, it has to reduce the content of active material, or be added
Inhibitor, this has just limited to the raising of battery electrical property.The present invention utilizes the good gas permeability of polytetrafluoroethylene (PTFE), by inside battery
The gas slowly generated discharges, and inside battery is made not generate gas accumulation.In this way reduce the stress of sealing ring, aging is existing
As reducing.And air pressure inside greatly reduces, and not will produce battery explosion phenomenon, is conducive to the security performance of battery, also breaks
The obstruction condition of the raising of battery electrical property.The present invention is to the degree of purity of raw material, box hat and conductive nail plated layer compact simultaneously
Degree, production process cleannes, production equipment material and wearability require all to substantially reduce, and reduce cost, and bigger is created for enterprise
Profit.
